一种新的改进算法，对采样数据先进行累加积分，然后做相关运算，可以有效地降低相关次数，使得捕获速度得到明显提高。这种研究方法也适用于其他系统的伪随机码的捕获研究。-A new improved algorithm, the sampled data points to accumulate first, then do related operations, can effectively reduce the number of relevant, making the capture rate

The function is used to generate a pseudo-random code generation of any GPS satellite 37 C / A codes Sv_id - satellite number cod - a vector comprising an output sequence g2s - vector containing the corresponding code phase values g2 for obtaining th
